Optimizer Messages (6000 through 6999)
SQL 6003
6003 The metadata table HISTOGRAMS or HISTOGRAM_INTERVALS
contains invalid boundary value value for column name. If you
have manually modified the metadata table, you should undo
your changes using the CLEAR option in UPDATE STATISTICS and
regenerate the statistics.
Cause. You have manually modified the metadata table, and now it contains an invalid
boundary value.
Effect. NonStop SQL/MX uses default histograms to compile the query. Therefore,
these might not be the best plans generated.
Recovery. Undo your changes using the CLEAR option in UPDATE STATISTICS and
regenerate the statistics.
SQL 6004
6004 The metadata table HISTOGRAM_INTERVALS for column clumn
does not have intervals intervale_number #1 and
interval_number #2 in order. If you have manually modified
the metadata table, you should undo your changes using the
CLEAR option in UPDATE STATISTICS and regenerate the
statistics.
Cause. You manually modified the metadata table and it now contains an invalid
boundary value.
Effect. NonStop SQL/MX uses default statistics to generate plans. Therefore, these
might not be the best plans generated.
Recovery. Undo your changes using the CLEAR option in UPDATE STATISTICS and
regenerate the statistics.
SQL 6007
6007 Multi-column statistics for columns names from table
name were not available; as a result, the access path chosen
might not be the best possible.
Cause. Statistics are not available for the multicolumn join you are performing.
This message appears when the user has not updated statistics for column names and
when the rowcount in table name is more than the value of the defaults table constant
HIST_ROWCOUNT_REQUIRING_STATS. If you want to suppress this message, set
that value to a very large number, and you will see this message only for tables with
more rows than that, and for which there are no updated statistics.
Effect. None. This is a warning message.
